HORSESHOE-CALK.

SPECIFICATION forming part of Letters Patent No. 626,743, dated June 13, 1899. Application tiled September 3, 1898. Serial No. 690,162. (No model.)

T0 a/ZZ 2071.077?, it muy concern:

Be it known that I, FRANK D. WILT, a citi- Zen of the United States, residing at Allentown, in the county ot' Lehigh, State of Pennsylvania, have invented certain new and useful Improvements in Horseshoe Calks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to removable calks for horseshoes, and particularly to a calk which can be secured in position by a single locking device.

The invention has for its object to provide a construction in which the heel-calks are movable and are thrown into and held in their locking position by a single device.

The invention has a further object to simplify and improve the construction of toe-calk whereby the same can be readily removed and replaced for the purpose of sharpening.

The invention has also for its object to improve the details of construction, as hereinafter disclosed; and other and further objects of the invention will be apparent.

In the drawings, Figure l is a bottom plan of the calk applied to a horseshoe. Fig. 2 is a top plan view. Fig. 3 is `a Vertical section on the line 3 3 of Fig. l. Fig. 4 is a detail perspective showing the toe-calk partly removed. Fig. 5 is a similar view of the modified construction of toe-calk applied to a plate, and Fig. 6 is a perspective of a tool particularly adapted for use in connection with this calk.

Like letters of reference indicate like parts throughout the several figures of the drawings.

The letter A designates a horseshoe of ordinary form and construction, which may be provided upon its upper surface, next the hoof to which it is applied, with beveled or reduced portions A. The movable calks are carried upon a plate B, which plate is provided with a central aperture B and with oppositely-located apertures B2, the latter being for the reception of pivoting-bolts C, which secure in position the angle-levers C'. These levers are suitably recessed at their outer ends to engage the shoe and at their inner ends are provided with arms C2, having curved faces next the toe of the shoe. These arms C2 may be actuated to force the levers C into contact with the shoe by any suitable device bearing thereon-for instance, a cam D, which may be provided with an angular recess Dj for the reception of a tool and with an exteriorlythreaded sleeve D2, which passes through the plate B and is adapted to receive a securingnut D3. This cam when secured in position can be rotated by the insertion of an angular tool in the aperture D', and will thus act upon the arms C2 of the angle-levers C and force the outer ends of said levers into'c-ontact with the shoe.

Any suitable form of toe-calk may be used in connection with the invention; but I have illustrated in this case a desirable form and a modification thereof. In the preferred form the plate B may be provided with an angular aperture B3 at its toe portion having beveled walls, as shown in Fig. et. The toe-calk E is provided with a dovetailed flange E', adapted to fit the aperture B3 and provided upon its upper surface with an engaging hook E2, adapted to receive the edge of the shoe at the toe portion thereof. The calk is also provided With an aperture through which the sleeve D2 of the cam D passes, and the calk is thus clamped in position by the nut D3, applied to the sleeve. This mode of mounting the calk renders the same readily removable for the purpose of sharpening or replacement, and when in position the same is rmly held against any movement upon the plate or shoe.

In the modification shown in Fig. 5 the toecalks F may be formed integral with the plate B or threaded into a flange F. Either of the foregoing forms of /toe-calks may be used without affecting the operation of the anglelevers, which carry the heel-calks G. These calks may be integral with the levers or threaded therein, if desired.

For the purpose of conveniently operating the several parts of the calks I have provided a novel tool H, which is formed at one end with a wrench H, adapted to engage the faces of the securing-nut D3, and at its opposite end with an angular key H2 of suitable size to fit the angular recess D in the cam D, and thus rotate the cam. Above the key H2 a scraper or cleaner H3 is provided, which can be used for the purpose of removing dirt or other substance from the parts of the call; when the same become clogged. It will be seen that with the use of this single tool any person can readily apply the calli to the shoe or remove the same. After the cam has been set by the use of the 'key I-I2 the nut D3 can be tightened by the Wrench H' and the parts thus firmly locked in position.

It is obvious that numerous changes can be made in the construction of the several calks and other details of the invention without affecting the spirit thereof as deiined by the appended claims. Y

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a removable calk, the combination of a plate, levers pivoted thereto, arms extending at an angle to said levers at their pivoted ends, and a rotary device carried by said plate i for simultaneously engaging said arms; substantially as specified.

2. In a removable calk, the combination of a plate, levers pivoted thereto, arms extending at an angle to said levers at their pivoted ends and a rotating device adapted to bear upon the arms extending lfrom said levers; substantially as specified.

3. In a removable calk, the combination of a plate, levers pivoted thereto, and a rotating cam located on said plate between said pivoted levers and adapted to engage each of said levers; substantially as specified.

4. In a removable calli, the combination of a plate, levers pivoted thereto, arms extending at an angle to said levers at their pivoted ends, a unitary device adapted to bear upon the arms extending from said levers, a hook carried by the toe portion of said plate, and calks located upon the outer ends of said levers; substantially as specified.

5. In a removable calk, thecombination of a plate, angle-levers pivoted thereto, a rotating cam adapted to engage said angle-levers,

an eXteriorly-threaded sleeve extendingfrom said cam, and a nut threaded upon said sleeve; substantially as specified.

6. In a removable calk, the combination of a plate, angle-levers pivoted thereto, a unitary rotating device adapted to engage said angle-levers, a removable toe-calli, a sleeve extending from said device and through said plate and calk, and a nut threaded upon said sleeve; substantially as specified.

7. In a removable calk, the combination of a plate provided with attaching means and having at its toe portion a recess, a calk provided With the dovetailed flange upon its upper surface and adapted to t in said recess, and a hook formed upon said flange; substantially as specified.

8. In a removable calk, the combination of a plate provided with attaching means and having at its toe portion a recess, a calli provided With a dovetailed flange upon its upper surface and adapted to iit in said recess, a hook formed upon said flange, an operatingcam provided with a sleeve having an angular aperture and passing through said plate and calk, and a nut threaded upon said sleeve; substantially as specified.

9. The combination With a horseshoe having reduced portions at its toe and heel, of a n plate provided With'a hook to engage said toe portion and with opposite pivoted levers 1 adapted to engage said heel portions, arms extending at an angle to said levers at their pivoted ends and a rotary locking device adapted to engage said arms and simultaneously force said levers into engagement With the shoe; substantially as specied.

In testimony whereof I affix my signature in presence of two Witnesses.
